A complete BCG-based sensing component that comprises the sensor, microcontroller and a Wi-Fi transceiver

Targeted for software solution- and service providers and OEM system integrators

BCGMCU Reference Design

Reference design with pre-programmed MCU and high sensitivity SCL3300 inclinometer

Description

The new bed sensor technology is based on the Ballistocardiographic (BCG) principle. When the heart pumps blood there is a recoil effect to the opposite direction. This means that when e.g. lying on a bed, the entire bed will be subject to micro movements due to the blood flow. We use an ultra-sensitive Murata accelerometer to capture this signal. A microcontroller with a specially made algorithms are able to extract heart rate and many other vital signs from the signal.
